Those are awesome, especially the sparring!
This is a very rare look at Toyoma Ryu Kenjutsu sparring.. It's not traditional kendo (kenjutsu), which is very fast and focuses more on scoring points than killing blows; this is Toyoma Ryu, which is something like the art of the perfect cut. This art is almost never used to spar, since it is very dangerous (note the full armor). This (way too short) clip is probably much more akin to an actual duel between samurai than any other video I have ever seen.
